Does this still happens in 2.6.15? Set this as "NEED MORE INFO" - the reporter doesn't seems to be ping-able. If someone can reproduce this in latests versions please reopen Please reopen this bug if it's still present in kernel 2.6.16. |
The kernel printed out the following when I tried to unmount my USB keychain. I have *not* been able to reproduce this bug consistantly. I hope that the following is useful. By the way, this happened after the keychain had been mounted, but not used for about half an hour. If you're interested, it is a Memorex 512 MB keychain using FAT32. I mounted /dev/sda (not sda1 like my other fried one) for it to work. kernel BUG at mm/slab.c:1382! invalid operand: 0000 [#1] PREEMPT Modules linked in: usb_storage sd_mod scsi_mod rtc ohci_hcd CPU: 0 EIP: 0060:[<c013f409>] Not tainted EFLAGS: 00010202 (2.6.8-gentoo-r3) EIP is at kmem_cache_create+0x3b9/0x550 eax: 00000032 ebx: c13adc50 ecx: c0479018 edx: c03a9458 esi: d096f68f edi: d096f68f ebp: c13adb60 esp: cfeffd2c ds: 007b es: 007b ss: 0068 Process khubd (pid: 21, threadinfo=cfefe000 task=cfed1100) Stack: c036ec5c d096f680 00000020 00002000 cfeffd4c c13adb9c ffffffff ffffffe0 000000a0 cfeeac00 d09799e0 cfeeac0c d0979a08 d0966384 d096f680 00000160 00000020 00002000 00000000 00000000 000001d8 cfeeac00 cfeeadd8 d0956920 Call Trace: [<d0966384>] scsi_setup_command_freelist+0x74/0x100 [scsi_mod] [<d096745b>] scsi_host_alloc+0x1ab/0x2b0 [scsi_mod] [<d0941f34>] usb_stor_Bulk_max_lun+0x74/0xc0 [usb_storage] [<d094338e>] usb_stor_acquire_resources+0x6e/0x130 [usb_storage] [<d094374b>] storage_probe+0x13b/0x240 [usb_storage] [<c028397a>] usb_probe_interface+0x5a/0x60 [<c025450f>] bus_match+0x3f/0x70 [<c0254581>] device_attach+0x41/0xa0 [<c025485b>] bus_add_device+0x5b/0xb0 [<c0253611>] device_add+0xa1/0x130 [<c028ae3e>] usb_set_configuration+0x2de/0x460 [<c0285d24>] usb_new_device+0xb4/0x170 [<c0286a12>] hub_port_connect_change+0x212/0x400 [<c02848d8>] clear_port_feature+0x58/0x60 [<c0286e75>] hub_events+0x275/0x3c0 [<c0286ff5>] hub_thread+0x35/0x110 [<c0119a40>] autoremove_wake_function+0x0/0x60 [<c0105ade>] ret_from_fork+0x6/0x14 [<c0119a40>] autoremove_wake_function+0x0/0x60 [<c0286fc0>] hub_thread+0x0/0x110 [<c0103d91>] kernel_thread_helper+0x5/0x14 Code: 0f 0b 66 05 73 e5 36 c0 8b 0b e9 63 ff ff ff 8b 47 34 c7 04 /proc/bus/usb/devices includes T: Bus=02 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 2 Spd=12 MxCh= 0 D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1 P: Vendor=0d7d ProdID=1400 Rev= 0.02 S: Manufacturer= S: Product=Memorex TD 2B S: SerialNumber=07470E081240 C:* #Ifs= 1 Cfg#= 1 Atr=80 MxPwr=200mA I: If#= 0 Alt= 0 #EPs= 2 Cls=08(stor.)
